Last friday my partner left her week old gaming PC idling alone for some time, enough for W10 to put it into sleep mode as per the power settings. At some point during sleep mode the GPU power led above the power connector had started flashing. The PC wouldn't respond to wakeup signal from peripherals or even the power button. I tried holding down the power button to force shutdown but nothing happened.
So I did what I thought was the sensible thing to do and switched the PSU off, waited for the mobo RGB to go out, switched the PSU on again and pushed the power button.
A flash of RGB, some fans slightly jerked and then nothing, except the mobo RGB lighting stays on. I also noticed the PSU didn't make it signature "click" sound related to inrush current protection. After a failed attempt like this, the power button won't do anything unless I power cycle the PSU which leads me to believe that something is causing a safety feature to trip and it resets only by power cycling.
I also observed the GPU power led flashing once before and that was after waking the PC from sleep. And the led wouldn't stop flashing by turning off the PC and only stopped after power cycling the PSU. Otherwise the computer worked fine. No crashes, no performance problems, excellent thermals. Ran RDR2 without issues. The mobo RGB works whenever I switch the PSU on so it's getting some power at least.
I've tried the small stuff: disconnecting case fans, the fan hub, ARGB hub, and even everything except the power cord from the rear. I've also checked the GPU power connector and the 24pin connector. For the 8+4 plug I had to do with a visual check since my hand won't fit in the corner where it's plugged in but everything seems ok, the connectors are sitting flush with the socket. One last thing I could try before taking everything apart is maybe disconnecting the GPU power cable.
Now I know that if I'm going to figure this out myself, I'll probably have to breadboard the whole system, or take it to a shop since I've had my fair share of hardware puzzles lately, but is there anything else I could do before that, anything that blatantly suggests something specific or any known issues with the components listed below?
I should add that the PC was built by the retailer using parts I chose. I usually build my own but this was a gift to my partner so I thought it would be nice to just have everything ready.
I'm technically eligible to RMA the whole build, but that would require shipping the PC halfway across the country. It's a wonder it found its way to us in one piece. Anyway, they told me that if I can pinpoint the issue, I can also RMA just the affected part(s) so I wouldn't have to ship the whole thing.
